Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 4-(1,2,4-oxadiazol-3-ylmethoxy)benzaldehyde (CAS 1042775-08-5), a certified reference material (molecular formula C10H8N2O3, MW 204.18 g/mol) for analytical method development and quality control.
4-(1,2,4-oxadiazol-3-ylmethoxy)benzaldehyde (C10H8N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
